A list of articles showcasing innovative individuals and technologies working to build a sustainable economy that protects our planet.
Earth Day is celebrated every year on April 22 to help raise awareness around environmental issues and to help promote sustainability. First celebrated in the US in 1970 and then progressing to a global movement in the 1990s, Earth Day was established to inspire action in order to secure a stable future for our planet.
This has become ever more apparent in light of this year’s Intergovernmental Panel on Climate Change’s (IPCC) report, in which it has been stressed that the choices and actions implemented in this decade will have impacts “now and for thousands of years”. “More than a century of burning fossil fuels as well as unequal and unsustainable energy and land use has led to global warming of 1.1 °C above pre-industrial levels,” wrote the IPCC in a press release.
Curbing further global temperature rise beyond the 1.5 °C limit set by the Paris Agreement in 2015 is still technically feasible but will require deep, rapid, and sustained reductions in greenhouse gas emissions. “Mainstreaming effective and equitable climate action will not only reduce losses and damages for nature and people, it will also provide wider benefits,” said IPCC Chair Hoesung Lee. “This […] underscores the urgency of taking more ambitious action and shows that, if we act now, we can still secure a livable, sustainable future for all.”
In light of this “code red for humanity”, it can be difficult to see the forest through the (burning) trees, but Earth Day aims to cut through this smoke and mitigate disillusion by highlighting and celebrating the massive global efforts being undertaken to help protect the environment and enact real change by bringing these issues to the forefront of policy.
Invest in our planet
This year’s Earth Day theme is “Invest in our planet” where the collective effort of individuals, governments, and businesses are required to bring about a more sustainable and equitable world. This means moving away from an outdated reliance on fossil fuels and redirecting our efforts toward building an economy that protects our planet.
For this to happen, a significant societal shift needs to take place, with a push for more a circular economy based on green infrastructures, renewable energy, and sustainable practices.
As with many past economic revolutions, technology will play a central role and its inventors and innovators are the ones who will help bring about significant and tangible change. To help highlight the work being done all over the world, we’ve compiled some recent “Must reads” for this Earth Day, featuring important environmental policy topics and innovative technologies scientists are developing to help tackle the climate crisis.
