Any smart climate strategy will need to simultaneously move away from fossil fuels and protect biodiversity, including through carbon sink preservation and a shift toward sustainable agriculture.
The 142 fossil fuel producers collectively exceeded the limits on coal, gas and oil production required to achieve the Paris Agreement goals by between 63% and 70%.
One year away from the 2024 Olympic Games, the grim reality of climate change is impossible to deny. How do we make the mega-event sustainable and avoid the pitfalls of greenwashing?
Large stretches of the Arctic are carbon-rich peat bogs. As the region warms and dries, lightning strikes can spark underground fires that can burn for years.
There’s more to sustainability than net zero. Using green ammonia for fuel and as a way to transport hydrogen could add to nitrogen pollution that already exceeds safe planetary boundaries.
Shipping companies have billions invested in fleets that were built to last decades. Now, the US is calling for zero emissions by 2050, and the EU is raising the cost of fossil fuel use.
Speed limits are coming down to improve road safety. Expanding the policy to target high-carbon emission vehicles would be a simple and effective climate strategy.
