rank_countries_by_emissions

Rank countries by greenhouse gas emissions.

Uses Climate TRACE data covering 252 countries and 60+ greenhouse gases.
Returns country rankings with total emissions and optional sector breakdowns.

Args:
gas: Gas type to rank by (default co2e_100yr).
start: Start year filter.
end: End year filter.
sectors: Comma-separated sector filter.
continent: Continent filter.

Returns:
Ranked list of countries with emissions totals.

Parameter	Type	Required	Description
`gas`	`string`	optional	Gas type: 'co2', 'co2e_20yr', 'co2e_100yr', 'ch4', 'n2o'. Default 'co2e_100yr'. (default: "co2e_100yr")
`start`	`any`	optional	Start year (inclusive). Omit for all available years.
`end`	`any`	optional	End year (inclusive). Omit for all available years.
`sectors`	`any`	optional	Comma-separated sectors (e.g. 'power,transportation'). Omit for all sectors.
`continent`	`any`	optional	Continent filter: 'Africa', 'Asia', 'Europe', 'North America', 'Oceania', 'South America'.
