GreenStep turns invisible daily emissions into a number you can see, and then tells you the one swap that would cut your footprint the most. Log a bus ride, a beef burger or an evening with the AC on, and GreenStep shows your carbon footprint, tracks it against a daily budget, and recommends personalised swaps based on what you actually did this week.

Climate change is driven by billions of small daily decisions, but almost nobody can see the carbon cost of a commute, a lunch or a night with the air conditioning on. Without feedback, there is no learning loop. Most carbon calculators are long annual surveys that people fill in once and forget.

A 10-second daily habit tracker with a coach built in:

Log activities across transport, food, energy and shopping (with one-tap quick adds). See today's footprint against a daily CO₂e budget (a Paris-aligned default of 6.3 kg, adjustable to India or world averages). Learn from the 7-day chart, which shows which category dominates. Swap. The coach scans your real logs, finds the swaps that would have saved the most (e.g. petrol car → train for your 36 km of trips = −4.7 kg this week), and lets you pledge them. Pledges are converted into yearly savings and tree-equivalents. Stay motivated with a streak counter and badges.
