National Energy Conservation Day 2025 - Go Solar!
Tamil Nadu mandates EV chargers in parking, but coal-heavy grid power makes ‘clean’ travel misleading. True conservation means generating clean energy, reducing grid dependence, and cutting fossil fuel demand. Charge EVs with solar—conservation starts at the source.

Human Rights Day 2025
Human rights cover our everyday essentials: the right to breathe clean air, access safe water, live with dignity, and have a voice in the decisions that shape our lives. This #HumanRightsDay, let’s recognise that protecting the planet, ensuring justice, and upholding accountability are all part of protecting human rights.

Burning fossil fuels releases long stored carbon that heats up our planet
#FossilFuels contain carbon stored deep within Earth’s history & burning them releases gases that intensify the #GreenhouseEffect. Reducing our dependence on these fuels and transitioning to #RenewableEnergy is essential for stabilising global temperatures & safeguarding the future.

Helsinki vs Chennai - Design, not blame
In Helsinki, safety isn’t left to chance, it’s designed into every street.
The city has reimagined its streets by narrowing roads, widening pavements, adding trees, and building over 1,500 km of dedicated cycling paths - all to make walking and cycling safer and more inviting.
Chennai can take inspiration by identifying key pedestrian and school routes, redesigning junctions for slower vehicle speeds and creating a connected network of footpaths and cycle tracks.
UNEA: there’s no planetary resilience without tackling plastic pollution
The plastic pollution crisis is threatening our health and our planet.
As leaders meet in Nairobi for #UNEA, let’s remind them: there’s no planetary resilience without tackling plastic pollution.
We need a global instrument to regulate plastics that truly protects people and the planet.
World Soil Day 2025
Cities rise on concrete, but they survive on soil. Urban soils, alive with microbes, rich in biodiversity, storing carbon, filtering water, and cooling our streets, sustain life in every neighbourhood. Yet rapid expansion, land sealing, pollution, and neglect are cutting the ground from under our cities. Every green rooftop, every permeable pavement, and every patch of restored urban soil brings us closer to a healthier tomorrow.

Climate Denial - Narratives that delay climate action
Crisis denial shifts climate responsibility to the future, claiming action is only possible once we achieve greater wealth. In reality, delaying action makes solutions harder and more expensive. Climate justice demands we move now, not someday.

Lower the speed, lower the road fatality rates!
In Tamil Nadu, nearly 1 in 5 crashes and over 1 in 5 road deaths are caused by speeding. Children and senior citizens are the most at risk.
In Helsinki, lower speed limits backed by speed cameras helped bring deaths to zero.
It’s time for Chennai to slow down too. Enforce 30 km/h school zones and automated speed enforcement in Chennai. Small limits can save big lives.
National Pollution Control Day
Pollution is an invisible crisis: stealing our health, damaging our soils, and poisoning our waters. This #NationalPollutionControlDay, let’s bring visibility to this silent threat. Every cleaner choice, every stronger policy, every informed citizen adds up to a healthier tomorrow.
