Climate Challenge

Action "NOW"

After the Covid pandemic, international organizations have bombarded us with campaigns claiming that "now" is the time for action. But the painful reality is that the true moment for decisive action began over 30 years ago. Back then, climate models and scientists predicted today’s challenges with remarkable precision, yet their warnings were ignored.

For decades, global conferences have come and gone, filled with lofty goals and promises. Yet, the nations most responsible for pumping CO2 into the atmosphere have consistently turned away, refusing to acknowledge their role. Their negligence and inaction have brought us to this tipping point. Yes, sometimes science and politics are worlds apart, each functioning on its own level.

That is why I refuse to sugarcoat the truth about climate change. "Now" the challenges are staggering, and the chance to halt the process is small. At this stage, all we can do is try to slow down the consequences. It's too late to expect politicians and governments to take the right steps to solve the climate crisis.

Rethinking Humanity’s Path Forward

Despite the cruel reality of climate change, humanity must find ways to navigate these challenges and mitigate their consequences. While some industries across the globe are making important efforts, we know these actions alone cannot lead us to a safe future if we persist with our current production model.

Humanity’s most profound transformation will come from becoming mindful eco-conscious inhabitants of planet Earth.

It makes no sense to elevate economics above the biosphere.

David Suzuki

What can we do? In fact, we need a "must" and a "now" _ Yes, we must act now and we should start to work in communities and reach systematically our environmental goals taking the right steps.

Here are 12 essential actions to reduce our impact on the planet and reduce the CO2 emissions (UN, Actions for a Health Environment, 2025):

1. Save energy at home

Much of our electricity and heat are powered by coal, oil and gas. Use less energy by reducing your heating and cooling use, switching to LED light bulbs and energy-efficient electric appliances, washing your laundry with cold water, or hanging things to dry instead of using a dryer. Improving your home’s energy efficiency, through better insulation for instance, or replacing your oil or gas furnace with an electric heat pump can reduce your carbon footprint by up to 900 kilograms of CO2e per year.

2. Change your home's source of energy

Ask your utility company if your home energy comes from oil, coal or gas. If possible, see if you can switch to renewable sources such as wind or solar. Or install solar panels on your roof to generate energy for your home. Switching your home from oil, gas or coal-powered energy to renewable sources of energy, such as wind or solar, can reduce your carbon footprint by up to 1.5 tons of CO2e per year. Learn more about why switching to renewable energy is key to tackling the climate crisis.

3. Walk, bike or take public transport

The world’s roadways are clogged with vehicles, most of them burning diesel or gasoline. Walking or riding a bike instead of driving will reduce greenhouse gas emissions -- and help your health and fitness. For longer distances, consider taking a train or bus. And carpool whenever possible. Living car-free can reduce your carbon footprint by up to 2 tons of CO2e per year compared to a lifestyle using a car. Learn more about how to green your travel.

4. Switch to an electric vehicle

If you plan to buy a car, if you really need to switch your car, so consider going electric, with more and cheaper models coming on the market. In many countries, electric cars help reduce air pollution and cause significantly fewer greenhouse gas emissions than gas or diesel-powered vehicles. But many electric cars still run on electricity produced from fossil fuels, and the batteries and engines require rare minerals which often come with high environmental and social costs. Switching from a gasoline or diesel-powered car to an electric vehicle can reduce your carbon footprint by up to 2 tons of CO2e per year. A hybrid vehicle can save you up to 700 kilograms of CO2e per year.

5. Consider your travel

Airplanes burn large amounts of fossil fuels, producing significant greenhouse gas emissions. That makes taking fewer flights one of the fastest ways to reduce your environmental impact. When you can, meet virtually, take a train, or skip that long-distance trip altogether. Taking one less long-haul return flight can reduce your carbon footprint by up to almost 2 tons of CO2.

I'm sure there are a lot of interesting places not far from your city that you didn't explore. Discover the new and the beauty close to you!

6. Reduce, reuse, repair and recycle

Electronics, clothes, plastics and other items we buy cause carbon emissions at each point in production, from the extraction of raw materials to manufacturing and transporting goods to market. To protect the climate, buy fewer things, shop second-hand, and repair what you can. Plastics alone generated 1.8 billion metric tonnes of greenhouse gas emissions in 2019 – 3.4 per cent of the global total. Less than 10 per cent is recycled, and once plastic is discarded, it can linger for hundreds of years. Buying fewer new clothes – and other consumer goods – can also reduce your carbon footprint. Every kilogram of textiles produced generates about 17 kilograms of CO2e.

7. Eat more vegetables

Eating more vegetables, fruits, whole grains, legumes, nuts, and seeds, and less meat and dairy, can significantly lower your environmental impact. Producing plant-based foods generally results in fewer greenhouse gas emissions and requires less energy, land, and water. Shifting from a mixed to a vegetarian diet can reduce your carbon footprint by up to 500 kilograms of CO2e per year (or up to 900 kilograms for a vegan diet). Learn more about the connections between food and climate change.

8. Throw away less food

When you throw food away, you're also wasting the resources and energy that were used to grow, produce, package, and transport it. And when food rots in a landfill, it produces methane, a powerful greenhouse gas. So purchase only what you need, use what you buy and compost any leftovers. Cutting your food waste can reduce your carbon footprint by up to 300 kilograms of CO2e per year.

9. Plant native species

If you have a garden or even just a plant or two outside your home, check for native species. Use a plant identification app to help. And then think about replacing non-natives, especially any considered invasive. Plants, animals and insects depend on each other. Most insects will not eat non-native plants, which means birds and other species lose a food source. Biodiversity suffers. Even a single tree or shrub can offer a refuge – just remember to skip insecticides and other chemicals.

10. Clean up your environment

"The trash may not be mine, but this is my one and only planet."

Humans, animals and plants all suffer from land and water contaminated by improperly discarded garbage. Use what you need, and when you have to throw something out, dispose of it properly. Educate others to do the same, and participate in local clean-ups of parks, rivers, beaches and beyond. Every year, people throw out 2 billion tons of trash. About a third causes environment harms, from choking water supplies to poisoning soil.

11.Make your money count

Everything we spend money on affects the planet. You have the power to choose which goods and services you support. To reduce your environmental impact, choose products from companies who use resources responsibly and are committed to cutting their gas emissions and waste. If you have money that is being invested for you, through a pension fund for instance, it may be supporting fossil fuels or deforestation. Making sure your savings are invested in environmentally sustainable businesses can greatly reduce your carbon footprint.

12. Speak up

Speak up and get others to join in taking action. It's one of the quickest and most effective ways to make a difference. Talk to your neighbors, colleagues, friends, and family. Let business owners know you support bold changes – from plastics-free products and packaging to zero-emissions vehicles. Appeal to local and world leaders to act now. Climate action is a task for all of us. And it concerns all of us. No one can do it all alone – but we can do it together.
